Question

Sometimes, two atoms of the same element have different numbers of neutrons. What is this known as? Valence electrons Orbits Radiation Isotopes

Answer 1

They are isotopes!
Good day

Answer 2

Isotopes

Step-by-step explanation:

Atoms of the same element sometimes have different forms just as we have plants of the same species having different varieties. These atoms usually have the same number of protons in their nuclei but different number of neutrons. They are referred to as isotopes.

A good example of atoms of the same element having different number of neutrons is
`^1^4C` and
`^1^2C`. Both atoms have 6 protons but while the latter has 6 neutrons, the former has 8 neutrons.

Valence electrons, orbits and radiation do not come close as atoms of the same elements with different neutrons.

The correct answer is Isotopes.
